THERMODRAIN Water Gully Covers are designed to cover drainage or stormwater gully openings in infrastructure systems, protecting the drain while allowing water to flow freely into the channel. They are commonly used in stormwater drain trenches, industrial plants, basement car parks, podiums, cable trenches, and similar drainage applications.
THERMODRAIN WATER GULLY COVERS
THERMODRAIN Water Gully Covers are tested as per BS EN 124, IS1726 & AASHTO M306 standards for drainage and Utility services meeting all requirements of the code. THERMODRAIN Water Gully Covers are better performing than Cast Iron, Ductile Iron and RCC manhole covers.

1) What are THERMODRAIN Water Gully Covers used for?
-
2) What material is used for THERMODRAIN Water Gully Covers?These gully covers are made from FRP/GRP composite material — Fiber Reinforced Plastic / Glass Reinforced Plastic — a high-strength composite that combines glass fibers with thermoset resin to produce a lightweight, rigid, and durable cover that resists corrosion and environmental degradation.

3) How durable are THERMODRAIN Water Gully Covers?
-
THERMODRAIN Water Gully Covers are highly durable:
- They are tested to international standards such as BS EN 124, IS 1726 and AASHTO M306 for drainage covers and utility service applications.
- Their composite construction gives excellent resistance to corrosion, sewage, chemical attack, and UV degradation compared to metal or concrete.
- The covers offer high impact strength and flexibility, meaning they are less likely to crack under load compared with brittle materials.
- Available in load classes from 2.5 T up to E600 (approx. 60 tons), they are suitable for both pedestrian and vehicular traffic zones.

4) How do THERMODRAIN Water Gully Covers compare with cast iron gully covers?
-
THERMODRAIN FRP/GRP vs Cast Iron Water Gully Covers:
- Weight & Handling: FRP is significantly lighter and easier to handle than heavy cast iron, reducing installation labor and cost.
- Corrosion Resistance: FRP resists corrosion from water, sewage, salt, and chemicals, whereas cast iron will eventually rust and degrade without protective coatings.
- Brittleness & Safety: FRP is more flexible and impact-resistant, while cast iron is brittle and may crack or break under shock loading.
- Theft Resistance: FRP has essentially no scrap metal value, reducing theft risk, whereas cast iron is often targeted for scrap.
- Maintenance: FRP is self-pigmented and usually needs no painting, while cast iron often needs periodic repainting to prevent rust.
