What Causes Cracks In A Foundation?

Foundation cracks in Somerset are caused by a combination of soil movement, moisture, and structural pressure.

One of the most common reasons is settling or shifting soil beneath the property, especially on clay or poorly compacted ground. Water infiltration from poor drainage or rising groundwater can weaken the concrete over time.

Seasonal temperature fluctuations lead to expansion and contraction, while freeze-thaw cycles in colder months create pressure that can break through concrete. In some cases, construction flaws or uneven structural loads contribute to long-term cracking and movement.

What Are The Types Of Foundation Cracks?

Common types of foundation cracks in Somerset include:

• Horizontal cracks – Often caused by soil pressure and water damage, potentially signalling serious structural issues.
• Vertical cracks – Usually due to natural settling and shrinkage, often less severe but may require sealing.
• Diagonal cracks – Typically result from uneven foundation settling and may widen over time.
• Stair-step cracks – Found in brick or block foundations, indicating shifting or sinking.
• Hairline cracks – Minor surface cracks that occur due to curing concrete but should be monitored.

How Do I Know If A Foundation Crack Is Serious?

A foundation crack in Somerset may be serious if it’s widening, leaking, or causing visible interior damage.

Warning signs include cracks that are wider than 5mm, extend across multiple surfaces, or show signs of water intrusion. Inside the building, symptoms such as sloping floors, sticking windows or doors, and wall or ceiling cracks suggest movement of the foundation beneath.

How Much Does Foundation Crack Repair Cost?

Foundation Crack Repair in Somerset costs between £300 and £4,000, depending on the severity and repair method required.

The cost is influenced by the size and location of the crack, the underlying cause, and whether it’s a cosmetic issue or a structural concern.

Hairline cracks needing only sealing or injection may cost between £300 and £800. In contrast, structural cracks requiring reinforcement or underpinning can rise to £2,000–£4,000. Additional expenses may include engineering assessments, moisture control systems, or foundation waterproofing.

What Are The Methods For Repairing Foundation Cracks?

Foundation cracks in Somerset can be repaired using epoxy and polyurethane injection, which is ideal for sealing narrow to medium cracks, restoring strength and preventing leaks. For more serious structural issues, we may install carbon fibre strips to reinforce cracked walls.

Underpinning or wall bracing is used in severe cases to stabilise the foundation itself. We also offer waterproofing membranes, drainage improvements, and soil grading to reduce the risk of future damage.

What Is The Process For Foundation Crack Repair?

The foundation crack repair process in Somerset begins by analysing the crack to determine whether it’s active or dormant and if structural intervention is needed. Once the method is chosen, we prepare the area by clearing debris and ensuring a clean surface.

For injections, we seal entry points and apply the resin under pressure. For reinforcement or underpinning, we excavate as needed and install support systems. The area is then resealed and tested for strength and water resistance before the job is completed.

How Long Does Foundation Crack Repair Take?

Most foundation crack repairs in Somerset take between 2 hours and 2 days, depending on the size, complexity, and method involved.

Hairline crack injections may be completed within a morning, while larger repairs involving excavation or bracing can span several days. Variables such as weather, site access, and structural layout may extend the timeframe slightly.

How Can I Prevent Future Foundation Cracks?

Preventing future foundation cracks comes down to drainage, soil care, and proactive inspections.

Ensure you have a good gutter and downspout system that directs water away from the foundation. Conduct regular inspections for early signs of damage, especially after heavy rain or cold spells.

In some properties, soil stabilisation or improved landscaping may be necessary to reduce pressure on the foundation walls.
