JOPLIN, Mo. — Contractors will be able to take their concrete waterproofing project to the next level with TAMKO’s new TW-Drain 220, a drain mat designed with core and fabric construction to help keep water out of residential, multifamily and light commercial projects. 

TW-Drain 220’s unique design allows for quick and simple installation, according to the company. 

TW-Drain 220 may be used for above grade applications such as balcony/breezeways. TW-Drain 220’s dimpled drainage core and filter fabric help protect entry points from potential moisture penetration into buildings.

“With TAMKO’s TW-Drain 220, water flows through the dimpled core, rather than building up excess moisture within the concrete. This relieves hydrostatic pressure and leads to better protection for your project,” said Corporate Director of Waterproofing for TAMKO, Brandon Knobloch.

TW-Drain 220 comes in 50-foot rolls with a 4-foot width. TW-Drain 220 can be purchased now from TAMKO’s Columbus, Kan. manufacturing facility with nationwide availability. Mixed truckload orders may be placed with TAMKO’s extensive line of additional waterproofing products. More information may be obtained at
