Crack Treatment
Structural and non-structural crack stitching, V-groove polymer mortar filling, and PU chemical injection.
What Is Crack Treatment?
Cracks in concrete and masonry provide an open superhighway for water. We classify cracks as dynamic (moving) or static (dormant) and apply appropriate flexible polymer mortars or high-pressure expanding polyurethane resins.
At SAINI WATERPROOFING, our core philosophy is diagnosis before prescription. Rather than applying superficial coats that fail after a few months, our civil waterproofing specialists investigate the underlying structural dynamics—including capillary suction, structural expansion, and chemical degradation—to install a multi-layer impermeable barrier built to keep water out permanently.

Possible Waterproofing Systems for this Application
Polyurethane (PU) Liquid Membrane
Superior UV resistance, crack bridging elongation (>400%), and 100% seamless barrier over complex architectural contours.
APP Modified Bituminous Membrane
Torch-applied heavy-duty prefabricated sheet with non-woven polyester core, ideal under screed on large flat roofs.
Acrylic / Elastomeric Hybrid Coating
Breathable, solar heat reflective coating for external facades and medium-traffic terraces.
Cementitious Crystalline System
Insoluble microscopic crystal growth inside concrete pores to permanently resist high hydrostatic pressure.
Get Your Site Moisture & Crack Diagnostic
Our technicians carry digital moisture meters to test your surface on-site.
Our Standard Engineering Process
Every waterproofing system is applied following a 6-step civil engineering protocol to eliminate failure points and ensure maximum longevity.
Diagnostic Site Inspection
Moisture mapping, structural crack classification, slope calculation, and core sample assessment.
Surface Preparation & Profiling
High-pressure washing, mechanical grinding, and removal of dead coatings, algae, and loose laitance.
Crack & Joint Treatment
Polymer mortar V-grooving, PU sealant injection, and fiber mesh reinforcement across corner coves and parapets.
Primer & System Application
Deep-penetrating primer followed by multi-coat engineered membrane (PU, APP, Crystalline, or Elastomeric).
Critical Detailing & Drainage Sealing
Flashing terminations, pipe collar encapsulation, drain spouts, and expansion joint sealing.
Final Quality Inspection & Handover
24-48 hour flood/pond testing where applicable, dry film thickness (DFT) verification, and formal warranty issuance.
Before & After Project Transformation
Real photographic proof of deteriorated damaged structures restored to 100% watertight integrity.
Identified Failure Mode
Aged surface screed with open shrinkage fractures and pooling water penetrating the slab below.
Applied Engineering Solution
Surface mechanical grinding, PU polymer mortar crack sealing, and 3-coat heavy elastomeric membrane.
