Short answer
Assess drainage and the condition of existing materials to decide the best approach for your patio or paving project. Identifying whether a simple repair or a full replacement is needed protects your investment. Understanding the ground conditions aids in selecting appropriate materials and ensuring long-lasting results.
Address any rocking slabs and drainage issues immediately to prevent further damage and ensure safety.

How to recognise it
- Rocking slabs indicate instability and suggest foundation problems or insufficient compaction.
- Visible weeds emerging through joints show jointing compounds have degraded or failed.
- Persistent water pooling on the surface indicates drainage problems or improper gradient.
- Cracking in the grout between slabs signifies failed pointing and structural weaknesses.
- An uneven paving surface, with varying slab heights, points to an inadequately compacted sub-base.
- Slabs shifting from their original position suggest inadequate support or ground movement.
- Efflorescence, a white residue on slabs, highlights ongoing moisture and drainage issues beneath.
Common causes
- A poorly compacted sub-base allows slabs to rock and become unstable underfoot over time.
- Improper drainage design causes water to pool, leading to ponding and potential structural load issues.
- Using inadequate bedding materials like loose sand results in slabs settling unevenly or shifting.
- A wrong surface gradient prevents water runoff, which leads to standing water and surface damage.
- Faulty jointing permits water to penetrate and weaken the structure, promoting weed and moss growth.
What you can do yourself
- 01Measure the full area to determine material quantities needed, reducing waste and ensuring precise planning.
- 02Monitor water flow during heavy rain to understand natural drainage patterns, allowing for proper drainage planning in the design.
What the landscaper does
- Adjusting the base and rebedding the slabs resolves rocking issues, enhancing stability and safety for walkways.
- Replacing damaged slabs and materials restores the functional and aesthetic elements of the patio or paving area.
- Installing drainage solutions, such as channel drains or soakaways, effectively manages water away from surfaces.
- Improving the sub-base with compacted aggregate creates a stable foundation to reduce future movement and settling.
- Correcting slopes and gradients encourages natural water run-off, alleviating issues related to water pooling and damage.
How the job usually runs
- 01Excavate to the required depth to accommodate sub-base and drainage, ensuring a stable foundation for the paving slabs.
- 02Compact the sub-base with suitable aggregates, creating a robust platform and verifying stability with a level check.
- 03Lay paving slabs precisely to the design, maintaining consistent spacing and correctly aligned surface levels.
- 04Apply jointing compounds carefully between slabs to seal gaps and prevent water ingress and weed growth.
- 05Install dedicated drainage features, such as channels, to facilitate effective water management and prevent surface flooding.
What the price depends on
LandscapeEngine does not publish a fixed price. That is agreed with the firm you appoint. Differences usually come from:
- Access challenges can increase costs as they may require specialised equipment or manual handling.
- The type of paving material chosen affects costs due to differences in durability, appearance, and installation complexity.
- Preparation complexity, such as extensive excavation or dealing with poor soil, raises costs due to additional labour.
- Adding intricate features or patterns requires more skill and time, which may drive up the overall project cost.
- Existing landscaping or structural elements that require modification or removal can impact the project budget.

Questions
What should I do if my patio slabs are rocking?
Rocking slabs often indicate inadequate support or a failing sub-base. Address this issue promptly to avoid greater structural problems or hazards. A professional may need to lift and re-lay the slabs with a new or improved foundation. Ensure compaction is thorough to maintain stability. It's also wise to check that drainage is efficient, which can help in maintaining the slab position over time.
Why are weeds growing between my paving slabs?
Weeds growing between slabs suggest that the jointing compound has broken down or was improperly applied. This allows seeds to settle and thrive in the gaps. To fix this, remove existing weeds and debris, then apply a new jointing solution designed to prevent such growth. Consider polymeric sand or similar products which harden and resist weed emergence, enhancing the patio's appearance and longevity.
Should I repair or replace my old patio?
Deciding between repair or replacement depends on the extent of damage. Minor issues like a few cracked slabs or surface weeds might be fixed with targeted repairs. However, widespread problems such as significant rocking, drainage issues, or a failing base generally necessitate replacement to ensure safety and longevity. A professional assessment provides a clearer picture and may help in making an informed choice.
What factors should I consider when choosing patio materials?
Consider durability, aesthetic appeal, and maintenance needs when selecting patio materials. Natural stones offer timeless appeal but can be more expensive and require sealing. Porcelain is durable and low-maintenance. Assess the property's style to complement existing architecture. Also, consider the load requirements of the patio area, especially if it's intended for heavy furniture or foot traffic, to ensure the chosen material can withstand such use.
