Lake Washington Residence
residential
General contractor March-MacDonald was tasked with building a modern luxury home on the shores of Lake Washington featuring numerous high-end amenities, including an 18-car garage and a vehicle elevator.
March-MacDonald selected Seattle roofing and waterproofing company Axiom D7 to assist with the extremely complex below-grade waterproofing system.
- YEAR 2022
- SQUARE FEET 8,000
- LOCATION bellevue, wa
- Axiom Commercial Roofing, Seattle
Challenge:
The job is unique in that water levels fluctuate throughout the year—peaking in late summer. Since the foundation was to extend 4 feet below the high-water level of Lake Washington, it would be submerged for part of the year.
Another challenge for Axiom was that the plans called for a grand total of 1,157 rebar and plumbing penetrations through the waterproof membrane. Neither Carlisle nor Axiom has ever seen a membrane installed in between the grade beams and the structural slab.
Solution:
Axiom held discussions with structural engineers and geotechnical inspectors about how best to design the waterproofing system. In the end, Axiom and Carlisle Coatings and Waterproofing (CCW) collaborated to design a unique system, consisting of a durable CCW Miraweld thermoplastic membrane system that fully adheres to the structural concrete, which is poured on top.
The Axiom team also performed a unique under-slab water proofing covering 8,000 square feet.
General Contractor: March McDonald
System Type: Carlisle Coatings and Waterproofing
Results:
As of Fall, 2022, the job was completed. March-MacDonald and CCW were pleased with the waterproofing solution that Axiom provided and looks forward to the completion of this beautiful luxury home.
