Frequently Asked Questions
Expert insights, specifications, and practical advice to support engineers, contractors, and homeowners at every stage of a project.
Piling methods
What happens if ground conditions differ from the investigation report?
If unexpected conditions are encountered, works are paused, the issue is assessed, and a solution is agreed with the engineer and client before proceeding.
How long does piling usually take?
Most residential piling works are completed within a few days. Larger or more complex projects may take longer depending on scope and conditions.
How deep do piles typically go?
Pile depth depends on ground conditions and load requirements.It's determined using ground investigation data and confirmed as part of the piling design.
Does piling cause vibration or noise?
Some piling methods generate vibration or noise, but modern equipment and controlled installation techniques help keep this within acceptable limits.
Groundworks
Are ground beams and RC slabs inspected by Building Control?
Yes. Inspections are carried out at key stages and signed off as part of the Building Control process.
Are ground beams and slabs designed by a structural engineer?
Yes. All ground beams and slabs are designed by a structural engineer, including reinforcement details and load requirements.
What types of reinforced concrete slabs do you construct?
We construct both suspended and ground-bearing reinforced concrete slabs, depending on the engineer’s design.
When are ground beams required?
Ground beams are typically required where foundations are piled or where loads need to be distributed across multiple support points.
Site Preparation
Can drainage and site works be carried out alongside piling?
Yes. These works are often coordinated to improve efficiency and reduce overall programme time.
What does site preparation include?
Site preparation may include excavation, reduced level digs, formation works, access preparation, and spoil removal.
Do drainage works require Building Control approval?
Yes. All drainage works must comply with Building Regulations and are inspected where required.
What is a soakaway and when is it required?
A soakaway allows surface water to disperse naturally into the ground and is typically required where connection to a surface water sewer is not available.
