Drainage correction
Lifting a slab without correcting the drainage that caused it to sink is treating the symptom. Water finds the same path, erodes the same soil base, and the slab settles again. We fix both.
Downspouts that terminate at or near a concrete slab dump concentrated roof runoff directly onto the soil base. Over years, that water erodes and compacts the soil under the slab, creating the voids that cause settlement.
Front Range bentonite clay absorbs water and expands, then dries and contracts — pulling away from slab undersides as it shrinks. Drainage that keeps soil moisture stable dramatically reduces the shrink-swell cycle and the settling it causes.
Yard grade that slopes toward a driveway, patio, or foundation directs surface runoff under the concrete instead of away from it. This is one of the most common and most easily fixed drainage problems we see.
When expansion joints crack or fill with debris, water infiltrates the slab edges and saturates the soil base from above. Sealed joints are the last line of defense once the slab is level.
What we fix
Perforated pipe buried in gravel intercepts surface and subsurface water before it reaches your concrete's soil base. Redirected to a safe discharge point away from the slab.
We extend short downspouts or install underground discharge lines to move roof runoff at least 6 feet from any concrete slab — eliminating one of the most common causes of settling.
Yard areas sloping toward a slab are regraded to create positive drainage away from the concrete. Low-tech, highly effective, and often the most impactful fix per dollar.
Expansion joints and cracks sealed with flex-rated polyurethane caulk to stop water infiltration from above. The final step after lifting — locks in the repair.
The complete approach
We combine polyurethane foam lifting with drainage correction and joint sealing into a single visit when possible. You get a complete fix — not a repair that will need to be redone in five years because the underlying water problem was never addressed.
Not always. If the settling was caused by normal clay shrink-swell or engineered fill compaction — not an active water pathway — polyjacking alone is the right fix. We assess drainage conditions on every free estimate and only recommend correction work when the water source is identifiable and addressable.
Signs include pooling water near the slab after rain, downspouts terminating near the concrete, soft or saturated soil at slab edges, and settling that's concentrated on the downhill or low side of the property. We look for all of these during the free on-site estimate.
Simple fixes — downspout extensions, basic regrading — often add a few hundred dollars to a polyjacking job. French drain installation for more significant water problems runs higher depending on length and complexity. We quote everything together so you see the full picture before any work starts.
Often yes, especially for downspout work and minor regrading. French drain installation may be scheduled as a follow-up visit. We coordinate everything to minimize disruption.
