Light-duty drainage,
quick to lay.

T6 U-Shape Drain (Light)

The product

The light U-Shape Drain (T6) takes everything that works about our heavy line and puts it in a leaner section for lighter ground. It is the channel for storm water and cable ducts along footpaths, plazas and quiet streets — sealed, smooth-bored and quick to place.

A lighter unit is faster to handle and sits flush with finished paving, so the surface stays clean and even. Same sealed bore, same maintenance-free life — sized for where the load is people and not lorries.

Why precast

On a footpath or plaza you do not want an open trench and a curing slab holding up the paving. Precast lets the drainage keep pace with the surface — units arrive finished, lay quickly and seal as they go.

Where it's used

It carries storm water drains and power and telecommunication cable ducts along footpaths, public plazas, landscaped streets and service roads — wherever drainage has to be neat, flush and out of the way.

The same sealed channel as the heavy line, in a leaner section that is quick to place.

— FAQ

About the light (T6) drain.

Common questions on load, sizing and laying. For anything project-specific, send us your drawing.

01What load is the light (T6) drain for?

It's a light-duty T6 section for pedestrian and low-traffic areas — footpaths, plazas, landscaped streets and service roads. Where vehicles run over the channel, use our heavy (T25) drain, rated for a 5 T wheel load.

02What grade and reinforcement is it cast in?

High-performance concrete from M50 to M75, RCC reinforced, cast and strength-tested to IS standards in our Surat yard — the same sealed, maintenance-free bore as the heavy line, in a leaner section.

03What sizes and covers are available?

Square sections of 300 × 300, 450 × 450, 600 × 600 and 750 × 750 mm, plus 300 × 400 and 600 × 300/400/500, all in 2000 mm lengths. Covers come standard (perforated) or without hole for the 300, 450, 600 and 750 mm drains.

04Why does it sit flush with the paving?

The section is designed to seat level with finished paving so the surface stays clean and even. A lighter unit is also quicker to place.

05How are the units jointed?

A groove joint with mortar filling, on a 20 mm thick mortar bed over a levelled granular base — sealed against silt and infiltration, with the smooth bore keeping water moving.

06Can you cast a custom size?

Yes — customized sizes are available for mass quantity. Send a drawing with the section, grade and length and we'll cast to your exact spec.
