Basement, Underground Pit & Below-Grade Waterproofing

Basement, Underground Pit & Below-Grade Waterproofing for Agri Infrastructure

Agricultural facilities often include underground pits, basements, collection tanks, effluent chambers, and below-grade foundations. These structures are constantly exposed to soil moisture, groundwater pressure, and seasonal water table fluctuations.

Unlike surface seepage, below-grade leakage is typically caused by hydrostatic pressure — where water forces itself through concrete pores, cracks, and construction joints. Over time, this leads to structural deterioration, reinforcement corrosion, internal dampness, and contamination risks.

In agri-based facilities, underground seepage can affect grain storage, wastewater management systems, cold storage foundations, and processing units. Proper below-grade waterproofing is therefore critical to ensure structural safety and operational reliability.

Common Problems in Below-Grade Structures

• Groundwater seepage through basement walls

• Dampness in underground storage rooms

• Leakage in effluent collection pits

• Water accumulation around foundations

• Cracks in retaining walls

• Corrosion of reinforcement due to continuous moisture

• Soil erosion around foundation walls

If left untreated, these issues can compromise both building stability and hygiene standards.

Scope of Services

We provide:

• External basement wall waterproofing

• Negative-side waterproofing treatment

• Injection grouting for active leakage

• Construction joint sealing

• Bituminous membrane application

• HDPE membrane installation

• Crystalline waterproofing treatment

• Retaining wall waterproof protection

• Underground pit lining and sealing

• Drainage board installation for hydrostatic pressure control

Waterproofing Systems Used

1. Bituminous Membrane Systems

• Ideal for below-grade foundation walls

• High resistance to soil moisture

2. HDPE Waterproof Membranes

• Durable and long-lasting

• Suitable for high water table areas

3. Crystalline Waterproofing

• Penetrates concrete matrix

• Blocks capillary water movement

4. PU Injection Grouting

• Used for active leakage control

• Expands to fill cracks and voids

System selection depends on soil condition, water table level, and structural design.

Engineering & Technical Considerations

We evaluate:

• Groundwater level and pressure

• Soil type and drainage capability

• Foundation depth

• Crack severity and location

• Structural load and reinforcement condition

• Existing waterproofing performance

Proper engineering assessment ensures a permanent solution instead of recurring seepage issues.
