A Terre Haute man was injured when he was thrown from his vehicle after it rolled over a retaining wall Sunday evening.

Danny Corbett, 73, was taken to an area hospital for non-life threatening injuries, police chief John Plasse said.

The incident occurred about 7 p.m. at Sycamore Manor assisted living complex. Corbett told police he had stopped his vehicle and got out to pick up something he had dropped. Corbett said he thought he had put the vehicle in park, but it began to roll forward so he tried to get back inside to stop it. He was halfway inside the vehicle as it drove off the ledge and crashed below, throwing him to the ground. The retaining wall is about 6 feet high.

The vehicle continued for several feet before rolling to a stop.

Leclaire Park will be getting a retaining wall installed in the coming weeks.

Leclaire Park will be getting a retaining wall installed in the coming weeks.

Retaining wall, new sidewalk considered

Leclaire Lake is going to get a significant upgrade in the coming weeks.

As discussed at last weeks Administrative and Community Services Committee meeting, Public Works recommended the approval to award Keller Construction, Inc. the base bid amount of $124,124.33 for the installation of a retaining wall and replacement of the sidewalk.

The wall will be along the east side of the lake, parallel to Madison Avenue and will also include the removal and replacement of the sidewalk, removal and reinstallation of a concrete fence and removal and replacement of the storm sewer.

Alderman Will Krause said this park improvement is definitely necessary to improve the site.

Its got to get fixed and its going to be a park improvement, visually to the area. Aesthetically, I think it will also help cut down on our moss issue that we have on that side for numerous years now, Krause said.

The Leclaire Lake project includes a base bid of 325 feet of retaining wall installation and an alternate bid, which includes 421 feet.

The retaining wall, along with the other park improvements, will improve pedestrian mobility and safety along Madison Avenue and around the park as a whole.

City Engineer Ryan Zwijack said if approved by City Council, prior to the installation, the lake will need to be lowered to accommodate the contractors.

The lake will be slightly lowered to a level of five to six feet. They have a range at which they have to keep it so the contractors dont pump it all out and kill all the fish. They have to keep it within a certain range, Zwijack said.

The project received a total of three bids, with the base bid amounts ranging from $124,124.33 from Keller Construction, Inc., $139,240.41 from RCS Construction, Inc. and $143,259.60 from Stutz Excavating, Inc. The engineers estimate for the base bid was $150,000.

Following approval from Council, Director of Public Works Eric Williams said contractors are hoping to have the project completed before the school year starts.

By the time, if Council approves and contracts are executed, the (time) blocks I believe will be 30 to 45 days, Williams said. I know they were trying to get it done before school starts.

As discussion came to a close, aldermen Will Krause, Art Risavy and SJ Morrison took a vote.

Krause made the motion, seconded by Risavy.

The motion was subsequently approved at Wednesday's Council meeting.

A 15 foot section of wall is missing at Watertown's Thompson Park. The sight leaves strollers in the park stunned.

"Just shocking. I haven't seen anything like it in all the years I've walked up here," said Tim Shaugnessy, passerby.

The city engineer says this was discovered last weekend.

There's little doubt what happened. A drain pipe ran through the lower part of the wall. If it was broken, Mother Nature did the rest.

"All these heavy rains may have been undermining that wall and washing out the soil through it. The fact that it went was probably just a matter of time, really," said Justin Wood, city engineer.

Any fix looks expensive, but the first steps include careful measurements of the damage and coming up with options, such as...

"Placement of embankment fill to build it back up or building it back up with a retaining wall and then looking at the aesthetics, of course, with the Olmsted design," said Wood.

The famed Olmsted Company designed the park around 1900.

With so much of this stonework throughout the park, all of it about a century old, will this collapse lead to a closer look at it?

"I think that's fair to say. There's an enormous amount of stonework up there that needs to be maintained. And so that's something we need to continue to look at," said Wood.

And continue to hope for kinder treatment from Mother Nature.

1. Incorporate the Wall Into Your Lifestyle

Retaining walls are usually thought of as utilitarian and for merely holding back soil. But you can use them to create beautiful outdoor living spaces and incorporate multi-use spaces.

Retaining walls don't have to be perfectly straight. Add a curve to dress up a boring straight wall and to add a little more texture to your landscape. You can use a garden hose or large rope to set the layout of the curve, then use a shovel to cut through the soil to follow the curve.

Smaller retaining walls, such as those less than four feet, can be easily planned and created without worrying too much about structure. Larger walls above that height may need an engineer's touch. Also be sure to check with local codes before starting one more than four feet tall.

From a lower grade, you'll need to gradually step up the retaining wall to reach a greater slope. Do this in increments and plan for a slight offset for each course change.

Besides offering a consistent look, manufactured blocks and stones for retaining walls offer structural integrity and an even base with which to work. There is little guesswork in installing, plus you'll have less work to do making sure each course is level. Be sure to color match and space out uneven colored stones and blocks for a better look.

Dig out your base several inches below grade and tamp/compact it to level. Add any filler, such as gravel, before adding your first stones or blocks. Remember, the base sets the tone for the entire wall, so spend a lot of time in preparing this key component.

A retaining wall that has a slope dropping to it will need additional drainage at the base. Add gravel and a fabric-covered drainage pipe at the base. The fabric will help prevent clogging of the pipe — a key feature as you will not want to dig out the pipe later to unclog it.

For each course of stones and blocks, be sure to check for level. This will help maintain a sturdy and balanced wall, plus you'll keep an even and consistent look.

Backfilling as you go adds support in success layers, so as you add a new course of blocks or stones, backfill to match this level. Be sure to tamp in/compact the soil as well, so you don't have as much settling later.

Add cap blocks to the top row of a block or stone retaining wall. You can add a layer of masonry adhesive to hold them in place, then back fill. Or you can backfill as you go, then add the cap. Either way, it provides a nice finished look, much like edging added to a paver patio.

Wall Design

Retaining Wall Blocks Suppliers, Builders, Installers ...

Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope). They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses.

A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil.[1]

A basement wall is thus one kind of retaining wall. But the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top.[2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side. The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures.[3]

Every retaining wall supports a wedge of soil. The wedge is defined as the soil which extends beyond the failure plane of the soil type present at the wall site, and can be calculated once the soil friction angle is known. As the setback of the wall increases, the size of the sliding wedge is reduced. This reduction lowers the pressure on the retaining wall. [4]

The most important consideration in proper design and installation of retaining walls is to recognize and counteract the tendency of the retained material to move downslope due to gravity. This creates lateral earth pressure behind the wall which depends on the angle of internal friction (phi) and the cohesive strength (c) of the retained material, as well as the direction and magnitude of movement the retaining structure undergoes.

Lateral earth pressures are zero at the top of the wall and in homogenous ground increase proportionally to a maximum value at the lowest depth. Earth pressures will push the wall forward or overturn it if not properly addressed. Also, any groundwater behind the wall that is not dissipated by a drainage system causes hydrostatic pressure on the wall. The total pressure or thrust may be assumed to act at one-third from the lowest depth for lengthwise stretches of uniform height. [5]

Unless the wall is designed to retain water, It is important to have proper drainage behind the wall in order to limit the pressure to the wall's design value. Drainage materials will reduce or eliminate the hydrostatic pressure and improve the stability of the material behind the wall. Drystone retaining walls are normally self-draining.

As an example, the International Building Code requires retaining walls to be designed to ensure stability against overturning, sliding, excessive foundation pressure and water uplift; and that they be designed for a safety factor of 1.5 against lateral sliding and overturning.[6]

Gravity walls depend on their mass (stone, concrete or other heavy material) to resist pressure from behind and may have a 'batter' setback to improve stability by leaning back toward the retained soil. For short landscaping walls, they are often made from mortarless stone or segmental concrete units (masonry units).[7] Dry-stacked gravity walls are somewhat flexible and do not require a rigid footing.

Earlier in the 20th century, taller retaining walls were often gravity walls made from large masses of concrete or stone. Today, taller retaining walls are increasingly built as composite gravity walls such as: geosynthetics such as geocell cellular confinement earth retention or with precast facing; gabions (stacked steel wire baskets filled with rocks); crib walls (cells built up log cabin style from precast concrete or timber and filled with granular material); or soil-nailed walls (soil reinforced in place with steel and concrete rods).[8]

Cantilevered retaining walls are made from an internal stem of steel-reinforced, cast-in-place concrete or mortared masonry (often in the shape of an inverted T). These walls cantilever loads (like a beam) to a large, structural footing, converting horizontal pressures from behind the wall to vertical pressures on the ground below. Sometimes cantilevered walls are buttressed on the front, or include a counterfort on the back, to improve their strength resisting high loads. Buttresses are short wing walls at right angles to the main trend of the wall. These walls require rigid concrete footings below seasonal frost depth. This type of wall uses much less material than a traditional gravity wall.

Sheet pile retaining walls are usually used in soft soils and tight spaces. Sheet pile walls are made out of steel, vinyl or wood planks which are driven into the ground. For a quick estimate the material is usually driven 1/3 above ground, 2/3 below ground, but this may be altered depending on the environment. Taller sheet pile walls will need a tie-back anchor, or "dead-man" placed in the soil a distance behind the face of the wall, that is tied to the wall, usually by a cable or a rod. Anchors are then placed behind the potential failure plane in the soil.

Bored pile retaining walls are built by assembling a sequence of bored piles, proceeded by excavating away the excess soil. Depending on the project, the bored pile retaining wall may include a series of earth anchors, reinforcing beams, soil improvement operations and shotcrete reinforcement layer. This construction technique tends to be employed in scenarios where sheet piling is a valid construction solution, but where the vibration or noise levels generated by a pile driver are not acceptable.

An anchored retaining wall can be constructed in any of the aforementioned styles but also includes additional strength using cables or other stays anchored in the rock or soil behind it. Usually driven into the material with boring, anchors are then expanded at the end of the cable, either by mechanical means or often by injecting pressurized concrete, which expands to form a bulb in the soil. Technically complex, this method is very useful where high loads are expected, or where the wall itself has to be slender and would otherwise be too weak.

Soil nailing is a technique in which soil slopes, excavations or retaining walls are reinforced by the insertion of relatively slender elements normally steel reinforcing bars. The bars are usually installed into a pre-drilled hole and then grouted into place or drilled and grouted simultaneously. They are usually installed untensioned at a slight downward inclination. A rigid or flexible facing (often sprayed concrete) or isolated soil nail heads may be used at the surface.

A number of systems exist that do not consist of just the wall, but reduce the earth pressure acting directly on the wall. These are usually used in combination with one of the other wall types, though some may only use it as facing, i.e., for visual purposes.

This type of soil strengthening, often also used without an outside wall, consists of wire mesh "boxes", which are filled with roughly cut stone or other material. The mesh cages reduce some internal movement and forces, and also reduce erosive forces. Gabion walls are free-draining retaining structures and as such are often built in locations where ground water is present. However, management and control of the ground water in and around all retaining walls is important.

Mechanically stabilized earth, also called MSE, is soil constructed with artificial reinforcing via layered horizontal mats (geosynthetics) fixed at their ends. These mats provide added internal shear resistance beyond that of simple gravity wall structures. Other options include steel straps, also layered. This type of soil strengthening usually needs outer facing walls (S.R.W.'s Segmental Retaining Walls) to affix the layers to and vice versa.[9]

The wall face is often of precast concrete units[7] that can tolerate some differential movement. The reinforced soil's mass, along with the facing, then acts as an improved gravity wall. The reinforced mass must be built large enough to retain the pressures from the soil behind it. Gravity walls usually must be a minimum of 50 to 60 percent as deep or thick as the height of the wall, and may have to be larger if there is a slope or surcharge on the wall.

Cellular confinement systems (geocells) are also used for steep earth stabilization in gravity and reinforced retaining walls with geogrids. Geocell retaining walls are structurally stable under self- weight and externally imposed loads, while the flexibility of the structure offers very high seismic resistance.[10] The outer fascia cells of the wall can be planted with vegetation to create a green wall.

The blocks for this project have a locking flange which makes the installation easy. The interlocking blocks can be used to build walls up to 28 inches high. Follow the block manufacturer's instructions concerning wall height limits.

Plan your layout. Avoid having downspouts pointed at the retaining wall and, if it's against the house, keep soiland mulchwell below the siding.

Your retaining wall design will determine how you mark the area. To mark a freeform layout, use a rope or hose to outline the shape. Then use a shovel to mark the outline. For straight lines, mark the entire bed area with stakes, string and marking paint. Mark curved corners by tying a string to a stake that's equidistant to the edge creating a compass and spraying the curves with marking paint.

To determine how many blocks you'll need per row, divide the total length of the wall by the length of the block. To see how many rows you'll need, divide the ideal wall height by the height of the block account for the first row to be half-buried. See Planning for a Block Retaining Wall for more information on estimating project materials.

Before you buy materials or begin work, check local building codes and your homeowner's association regulations to see if there are any restrictions or requirements you need to follow. A permit may be mandatory in some areas.
