What we repair

Split tank outlets

Very common on Tankmasta tanks (though not limited to them). We have a tried and tested repair method for split outlets — our favourite repair for its success rate, learnt providing warranty repairs for Tankmasta in their final year of operation.

Split walls & bases

We're one of the few plastic welders equipped to weld from inside the tank — with the gear to drain the tank and the appropriate breathing equipment to do it safely.

Diesel & fuel tanks

Tractor and machinery fuel tank repairs — sometimes in the field, or removed if the damage needs it. Most tractor fuel tanks come off easily.

The honest word on poly repairs

When a weld is the right call, it's a quick, economical fix. But poly that's gone brittle from years of UV often cracks again near the repair — money down the drain. So every poly repair is assessed case by case: if a weld will genuinely last, we'll do it; if it's a band-aid, we'll say so and talk through what actually solves it — a tank liner for larger tanks, or replacement for smaller ones.

Send a few photos of the damage with your call and you'll get a straight answer about whether it's worth repairing.
