Foundation Repair Photo Album: Exterior Waterproofing and Piering in Brentwood, MO

This older home had concrete piers installed but they now have failed. The front stoop had settled as the piers settled and failed. A large unsafe gap making the front door useless was one of the first signs of a problem. Stair stepping cracks in the brickwork toward the rear of the home come next. As the foundation cracked, water began to enter the basement. An engineer was hired to design the solution for this home and we did the work as specified. The exterior drainage system do not utilize a sump pump since we could trench a discharge line downhill towards the street in front.

Before Photo of Exterior Waterproofing and Piering

This is the gap in the front stoop due to concrete piers failing and settling. The front door could not be used.

Side View of the Yard

This is the side where we did the exterior waterproofing.

Concrete Pier Pipe

The rusted pipe below the white PVC is the concrete pier tube, one of several that failed.

Cracks in Brickwork

Stair stepping cracking through the bricks are one of the signs of a settling foundation.

Push Pier Ram

The hydraulic ram is a smooth operation for installing the push piers, it does not "jerk" the structure.

Pier ram with gauge and regulator

The ram regulator allows the hydraulic fluid to bypass if pressure builds so as to keep the smooth installation of the pier tubing from "jerking" the home.

Pier Brackets

Two pier brackets are on their side but you can see the the "L" shape that one part of the "L" is placed directly below the foundation wall.

Two pier holes

The larger dug out area are where the push piers will go. The two rusty pipes are the locations of the failed concrete piers.

Corner Crack and our piers being installed

The cracking in the corner shows the settling affect and we are installing piers to correct.

More of our piers in the corner

More of our piers around the corner of the home.

More of our piers along the side

A couple more piers down the side of the home.

Waterproofing drain line downhill to the street

This exterior waterproofing did not need a sump pump since we were able to drain the water downhill towards the street.

Vertical Barrier

We installed a vertical water barrier along the foundation wall to keep water in the trench and out of the basement.

Drain Tile and rock covered by filter fabric

The waterproofing trench is filed with rock and several rows of drain tile which is covered by filter fabric. The fabric helps keep dirt from getting into the exterior waterproofing system. Just like an inside basement drain tile system, dirt can clog and ruin the working waterproofing system on the exterior too.

Filling the waterproofing trench

Notice the workers hand on the piping for one of the concrete pier that failed. After laying the fabric over the rock we fill the rest of the trench with dirt.
