Shivoham Fabtech manufactures high-performance HDPE Dimpled Drainage Boards (also known as Dimple Mats or Drainage Sheets)—an impermeable, vacuum-formed polymeric barrier engineered to relieve hydrostatic pressure and physically protect structural waterproofing systems.
Built to withstand massive earth pressures, our Dimple Drainage Board is manufactured from virgin High-Density Polyethylene (HDPE) molded into a continuous pattern of raised geometric dimples (studs). When placed against a subterranean concrete wall, these dimples create a permanent, high-volume air gap between the structure and the surrounding wet soil.
This continuous void space breaks the capillary wicking of moisture and allows groundwater to depressurize and drain rapidly down to the perimeter footing system. Available with a thermally bonded non-woven geotextile filter, the dimple board prevents soil fines from clogging the drainage gap, ensuring your basements, tunnels, and retaining walls remain permanently dry and structurally sound.
Dimpled Drainage Board – Available Range
Dimpled Drainage Boards are available in multiple configurations to suit varying burial depths and compressive loads. We manufacture customized dimple heights for specific flow capacities, available strictly as impermeable protection boards or laminated with non-woven geotextiles for active soil filtration. Configuration: Single Board or Non Woven Geotextile Laminated (Geocomposite)
Dimpled Drainage Board — Technical & Performance Properties
Absolute Hydrostatic Relief
Water pressure is the primary cause of subterranean structural cracks. The rigid 3D dimple structure creates an unstoppable gravity-fed drainage plane. It rapidly channels heavy inbound groundwater directly down to the weeping tiles or footer drains, entirely stripping hydrostatic pressure away from the concrete wall.
Waterproofing Membrane Protection
During construction backfilling, sharp gravel, rocks, and heavy compaction machinery can easily puncture expensive liquid or sheet-applied waterproofing membranes. The tough, rigid HDPE dimple board acts as an impenetrable physical shield, guaranteeing the underlying primary waterproofing envelope is never compromised.
High Compressive Strength
Engineered for deep-burial earth pressures, our heavy-gauge HDPE dimple drainage boards resist structural collapse and maintain a functional drainage void under massive soil overburden. This prevents the dimples from crushing flat — a common failure in cheap, thin-gauge plastics buried behind deep basement and retaining walls.
Why do Engineers Specify Drainage Dimple Board?
Built for Infrastructure That Lasts
Modern civil and commercial structures demand foundation protection that will outlive the building itself. Shivoham Fabtech’s Dimple Board provides a brutal, physical defense against water ingress and backfill damage.
Applications in Civil Infrastructure
Quality & Testing Certifications
Our products undergo rigorous testing at NABL accredited laboratories to certify puncture resistance, compressive strength (crush resistance), and in-plane flow capacities, ensuring full compliance with stringent commercial waterproofing and geotechnical standards.
