What We Do

Full-Service Waterproofing for Any Property

We handle every type of water intrusion problem across Riverside, San Bernardino, and the surrounding communities. No matter where the water is coming from or what type of property you own, we have the tools and the experience to solve it.

Basement Waterproofing

Water in your basement is never just a basement problem. It is a sign that something is wrong with how water moves around your foundation, and if it is left alone, the damage spreads. We start by identifying exactly where the water is entering and what is driving it there. We then seal cracks, apply waterproofing membranes, and put drainage solutions in place to keep water from building up against your foundation. Our basement waterproofing services in Riverside and San Bernardino Counties are built to stop the problem at the source, not just mask the symptoms.

Deck Waterproofing

A deck that is not properly waterproofed will not last. Water works its way into the surface, expands and contracts with temperature changes, and begins breaking down the material underneath. Over time, you end up with soft spots, rot, structural damage, and a deck that is no longer safe. We apply professional-grade waterproofing membranes that seal the surface completely and hold up against UV exposure, foot traffic, and moisture year-round.

Balcony Waterproofing

Balconies are exposed to the elements every single day and are one of the most common places water damage begins on residential and commercial buildings. A small crack or a failing seal can let water work its way into the structure beneath the balcony surface, causing damage that is far more expensive than the original waterproofing would have been. We inspect, prepare, and waterproof balconies on all types of buildings so that your structure stays protected no matter what the weather brings.

Concrete Crack Injection & Repair

Concrete cracks are one of the most direct paths for water to enter a building. Even a hairline crack in a foundation wall or floor slab can let in enough water to cause serious damage over time. We use proven injection methods to fill cracks from the inside out, bonding to the concrete and creating a seal that stops water from getting through. This is one of the most effective and long-lasting solutions for foundation leaks, and it is far less disruptive than excavating or replacing sections of concrete.

Silicone Roof Coatings

A silicone roof coating is one of the smartest investments a commercial property owner can make. It adds a seamless, fully waterproof layer directly over your existing roof surface without the cost and disruption of a full tear-off and replacement. It reflects heat, which lowers cooling costs, and it seals existing cracks and seams that would otherwise let water in. Silicone coatings are ideal for the flat and low-slope roofs common on commercial buildings throughout Riverside and San Bernardino Counties.

Elastomeric Stucco Coatings

Stucco is a common exterior finish in Southern California, and it looks great when it is in good shape. Over time, though, stucco develops cracks from heat, settling, and weather exposure. Those cracks let moisture in behind the surface, which can lead to mold, rot, and damage to the building's framing. An elastomeric stucco coating stretches with the surface to bridge existing cracks and prevent new ones from forming. It creates a tough, waterproof barrier that protects the building while also refreshing the exterior appearance.

Expansion Joint Caulking & Sealing

Expansion joints are built into concrete structures to allow for natural movement, but they are also one of the most common places water finds its way in. Old or failed caulk shrinks, cracks, and pulls away from the joint, leaving a gap through which water can enter. We remove the old material, clean and prepare the joint, and install high-performance sealants that flex with the structure and keep water out for the long term. This service is critical for parking structures, commercial buildings, and any property with large concrete surfaces.
