At TWC Phoenix, waterproofing isn’t an afterthought—it’s our foundation. As New England’s oldest waterproofing contractor, we’ve been protecting structures from moisture and deterioration since 1905. From modern commercial towers to historic landmarks, our waterproofing services are tailored to meet the specific needs of each building and its environment.
We support both new construction and complex retrofit projects, delivering long-lasting, code-compliant solutions that meet today’s performance standards. Our expertise spans office buildings, hospitals, universities, parking structures, and more.
Our Waterproofing Capabilities Include:
Injection Work
Stabilize compromised concrete and fill voids under slabs or behind foundation walls using low-viscosity materials that stop leaks and strengthen structures.
Expansion Joints
Install watertight, pre-compressed, mechanical, or aesthetic internal and external expansion joints tailored to your building’s requirements.
Joint Sealants
Apply high-performance sealants for windows, sanitary spaces, or other critical areas requiring durability and precision.
Cleanrooms
Seal new or renovated cleanroom environments to the highest standards.
We also specialize in preserving historic materials and addressing regional challenges such as freeze-thaw cycles, coastal humidity, and aging infrastructure. TWC Phoenix delivers durable, compliant solutions that reduce long-term risk, save on repairs, and protect your investment.
