Waterproofing Contractors in Riverside, CA

Below-Grade Waterproofing

Water can enter commercial buildings through below-grade walls, foundations, and other areas exposed to moisture. Syntech provides below-grade waterproofing as part of its specialty waterproofing services.

The appropriate repair depends on the source and extent of the water intrusion, so identifying the problem is an important first step.

Plaza & Planter Waterproofing

Plazas and planters can develop recurring water-intrusion problems when waterproofing systems, joints, or surrounding surfaces begin to fail.

Syntech provides planter and plaza waterproofing as part of its commercial building-envelope services, helping property teams address water intrusion while protecting surrounding building components.

Deck & Balcony Waterproofing

Deck and balcony areas are exposed to weather and regular use, making waterproofing an important part of maintaining these building components.

Syntech provides deck and balcony waterproofing and coatings for commercial properties, with solutions selected according to the condition of the existing system and the source of the water intrusion.

Concrete & Masonry Waterproofing

Water intrusion can also affect concrete and masonry assemblies. Cracks, spalls, deteriorated joints, and other openings can create pathways for moisture.

Syntech combines waterproofing with concrete and masonry repair capabilities, including concrete crack and spall repair, masonry spalling and re-pointing repairs, and structural concrete repair.

Crack Injection

Some water-intrusion problems require targeted crack repair rather than a broad waterproofing application.

Syntech provides urethane and epoxy crack injection as part of its specialty waterproofing services. These methods can be used to address appropriate concrete crack and leak conditions, depending on the specific building assembly and failure.

Building-Envelope Water Intrusion Repair

Not every leak originates where the water first appears.

Water can move through joints, windows, walls, decks, concrete, roofing systems, and other components before becoming visible inside a building. Syntech's building-envelope services include leak investigation and testing, window leak repairs, joint resealing, sealants, coatings, waterproofing, and related restoration work.
