Directional drilling explained step by step: pilot bore, back-reaming and pullback, plus the UK depth, clearance and permit rules that govern the bore.
What directional drilling is, where HDD fits on UK utility schemes, and the pipe, survey and street works constraints that decide if a bore works.
Why UK leak detection prices range from under £100 to £1,500, what actually drives the cost, when detection is free, and what trace and access covers.
The signs of an underground water leak, from high bills and low pressure to damp ground, plus two meter tests and who is responsible for fixing it.
Whether it's a self-lay scheme, a burst main at 2am, or a reinstatement programme, we'd welcome the conversation. 40 years of getting it done, one phone call away.
