Detroit Foundation Waterproofing with BASF MasterSeal
When a foundation wall, plaza deck, or underground concrete structure needs waterproofing that holds for the life of the building, MasterSeal is the spec. Detroit Concrete installs the full system, substrate prep, primer, membrane, protection layer, to BASF protocol. Free written estimate on every job.
Not every concrete structure needs structural-grade waterproofing, but some absolutely do. A multi-storey foundation wall in Detroit's clay-heavy soil, a plaza deck poured over occupied retail space, a below-grade parking structure subject to road-salt infiltration from above: these are the conditions MasterSeal is built for. A pinhole in the membrane on a job like this is not a maintenance call, it is a structural event with real financial consequences.
Detroit Concrete installs MasterSeal as a BASF-system installer, meaning the prep sequence, primer selection, membrane thickness, joint detailing, and protection layer all follow BASF's published protocol. That compliance is what activates the system warranty, and we produce the documentation to support it. For projects where the engineer has specified a different brand, see Sika waterproofing systems or Ardex waterproofing as alternatives.
Sheet membrane, liquid-applied, or hybrid, the choice depends on substrate condition, exposure type, and how the project is sequenced. We confirm the product with the engineer before ordering.
Prepare the concrete substrate
The concrete surface is ground, cleaned, and brought to BASF's surface profile requirements. Existing cracks are repaired with a compatible filler; joint areas are isolated and detailed before membrane work begins.
Prime, then apply the membrane
BASF primer goes down first, then the MasterSeal membrane is applied at the engineered thickness. Every penetration, corner, and transition joint gets full detail treatment per the BASF installation guide.
Install protection layer and document
Where backfill or traffic will contact the membrane, the protection layer is installed before the slab or fill goes in. The completed system is photographed and documented for the BASF warranty file, then handed off ready for the next trade.

Why Structural Waterproofing Needs an Engineered Spec
A residential basement sealer and a MasterSeal below-grade membrane are not the same category of product. MasterSeal projects typically carry a structural engineer's stamp because the waterproofing is protecting load-bearing concrete, not just keeping a storage room dry. The engineer's drawings define which MasterSeal product applies, what thickness is required, and how transitions at footings and slab edges are detailed. Our job is to execute that spec precisely and produce the paperwork that lets the engineer sign off.
Detroit's freeze-thaw cycle adds another layer of pressure on below-grade concrete. Water that infiltrates a foundation wall in November can expand through the slab by March, widening cracks and compromising the structural assembly. A properly installed MasterSeal membrane, with the protection layer intact before backfill, stops that cycle before it starts. For grouting needs on the same project, BASF MasterFlow non-shrink grout handles equipment baseplates and structural bearing pads. For polished or coated interior concrete floors tied to the same build, see commercial polished concrete floors. Questions about what a waterproofing estimate covers are answered in our concrete estimate guide.
System types, structural engineer coordination, warranty and protection layer requirements.
Below-grade structural waterproofing on commercial or institutional projects, plaza decks over occupied space, and any application where the engineer specifies BASF. We install when MasterSeal is specified rather than recommending it over alternatives.
Most MasterSeal projects do, because they involve structural assemblies. The engineer specifies the product and the install detail; we deliver to that spec with documentation.
For below-grade and traffic-exposed applications, yes. The membrane needs physical protection from backfill or traffic; the protection layer is what keeps the membrane functional through service.
Yes, system warranty applies when installed by a BASF-system installer to BASF spec. We deliver the documentation that supports the warranty submission.
Depends on area and system. Foundation walls can be done in days; large plaza-deck systems with multiple layers stretch over weeks. The schedule is in the quote.
MasterSeal below-grade install on a structural foundation. Documentation supported the engineering review, install passed inspection. The system path was clean from spec through warranty.

★★★★★
Structural waterproofing with BASF spec on a complex below-grade project. The install matched the spec, documentation supported the audit. Real engineering-grade work.

★★★★★
Below-grade MasterSeal across a foundation, full system warranty in our project file. Dry through three springs of melt. Worth doing right at structural scale.
