AKWASWELL

A polyurethane-based caulk grade swelling paste, AKWASWELL is used primarily to seal rough surfaces in concrete construction joints. Swelling up to 500% of its initial volume when hydrated by water, it creates a positive seal and stops the flow of water through the joint and is suitable for low to moderate hydostatic pressure conditions.

• Technical Data Sheets

Helios Energy Research Facility

Berkeley, CA, USA

From design development to construction, CETCO’s expertise in waterproofing was called upon to ensure that the basement, housing expensive laboratory equipment, remains dry at all times. CoreFlex’s composite system also saved the added labor of a two-membrane installation process.

Mercy Hospital Plaza

St. Louis, MO, USA

To minimize building exposure, poor air quality, and odors, this occupied hospital utilized COREFLEX to waterproof the plaza deck prior to installing a GreenScapes vegetated roof system, hard-scape and water features.

Piper Tech Parking Deck

Los Angeles, CA, USA

Ronald McDonald House

Chicago, IL, USA

CETCO provided the complete watertight green roof assembly for the nation’s largest Ronald McDonald House. Protected by CETCO’s COREFLEX® waterproofing membrane, three GreenScapes^™ assemblies—intensive, extensive, and vegetated trays—were utilized to meet a challenging landscape design.

Sandpiper Run Plaza Restoration

Pawley's Island, SC, USA

This restoration application used an extensive GreenScapes^™ system with COREFLEX® waterproofing technology to create an ocean side lawn space for condo occupants. When used in restoration applications, CoreFlex® minimizes demolition, reduces building exposure and limits building down time.

Shady Hills Gymnasium and Parking Garage

Cambridge, MA, USA

The original spec called for ULTRASEAL below slab with a layer of VOLTEX DS installed over it to provide protection from subsequent concrete operations. However, once the dewatering of the site began, it became apparent that there would be significantly more water at a greater flow rate.

Wake Forest University Hosp. Plaza Deck Restoration

Winston-Salem, NC, USA

Restoration of the plaza deck was required for watertightness of the hospital space below and reopening of the emergency room entrance. COREFLEX was quickly installed over the leaking hot-applied rubber membrane to complete the project on time with minimal building exposure.
