G&G Concrete Waterproofing Inc.
Chemical Sealants effectively stopped leaks in this dam after 9 trailer-truckloads of cement and 6 months of work by another contractor failed.

At G & G we specialize in SEALING WATER LEAKS.

We solve your water leak problems with the finest quality chemical sealants applied under the supervision of Maine's first certified provider of this service.

With over 18 years of experience, we have successfully completed major subway repairs in New York City and Boston, sewage treatment plant repairs at Sheepshead Bay and the Brooklyn Navy Yards as well as dam repairs in Plattsburgh, New York and Central and Northern Maine.

We work with electrical utilities, transportation agencies, municipalities, and private companies to repair water leaks which otherwise drain thousands of unnecessary dollars from your budgets.

We succeed because we know what a permanent water leak repair requires in our climate: a sealant which is both durable and flexible, able to withstand the shifting, twisting, bending, and stretching which affect your installation. Therefore, we use chemical grouts with elastomeric and flexible properties which resist cracking and pulling apart due to shifting.
