Specialized Waterproofing for Temporary and Permanent Shoring Systems
We provide expert waterproofing services for shoring and shotcrete walls across Los Angeles, Pacific Palisades, and Malibu.
Our scope begins once shoring and excavation are complete — installing membranes, drainage, and detailing systems designed to protect below-grade structures from groundwater and hydrostatic pressure.
Purpose of Shoring Wall Waterproofing
Shoring systems such as soldier piles and lagging, soil nails, or shotcrete walls are essential for excavation stability — but they are not waterproof.
Once the permanent structural wall is formed against them, a dedicated waterproofing system must be installed to prevent water infiltration through cold joints, tie-backs, and substrate transitions.
We specialize in creating continuous, watertight barriers that integrate with the structural wall and foundation drainage systems, ensuring long-term moisture protection.
Our Waterproofing Systems for Shoring Walls
Shotcrete-Compatible Membranes
We install flexible waterproofing membranes compatible with both cast-in-place and shotcrete applications.
These membranes form a durable, bonded layer between the soil retention system and the new structural wall.
Blindside Waterproofing Systems
For projects using soldier piles and lagging or soil nails, blindside waterproofing is installed before the concrete pour.
These systems are designed to bond to the structural concrete, eliminating lateral migration of water.
Bentonite Panels & Composite Sheets
Self-sealing bentonite membranes provide excellent performance in confined conditions.
When hydrated, the bentonite expands to fill voids, protecting against leaks through tie-backs or irregular substrates.
Drainage & Protection Layers
We integrate vertical drainage composites and protection boards over membranes to relieve hydrostatic pressure and prevent damage during concrete placement or backfill.
Tie-Back & Penetration Detailing
Tie-backs, soil nails, and anchors create potential pathways for water.
Each is detailed and sealed using compatible materials to maintain full membrane continuity.
This includes:
Tie-back and nail head detailing
Cold joints between shotcrete lifts
Pipe sleeves and mechanical penetrations
Edge and corner transitions
Hydrostatic Pressure & Drainage Management
Our systems incorporate vertical drainage mats and footing drains to manage water buildup behind shoring walls.
By combining waterproofing and drainage, we reduce hydrostatic pressure, protect structural finishes, and ensure long-term system performance.
Surface Preparation & Installation
Before waterproofing installation:
Surfaces are cleaned and inspected for irregularities or laitance
Voids and honeycombs are patched with compatible materials
Terminations, overlaps, and penetrations are detailed per manufacturer specifications
Installed membranes are protected before the next concrete phase or backfill
Compliance & Quality Control
All systems are installed according to Division 07 – Waterproofing standards and manufacturer requirements.
Field conditions are verified before application, and documentation is provided for submittals or inspections.
