Caro Support

Supports for paving decking

When pavings are laid directly onto a sand/cement bed, the temperature extremes of frost, rain and direct sunlight, can cause the pavings to move over a period of time, and this could eventually lead to them lifting, sinking or cracking. Futhermore, this movement can even lead to damage or puncturing of the water proofing membrane.
Paving Supports
CARO SUPPORT is one of the most economical and simple ways of laying roof or terraced areas. This Polypropylene injection moulding raises the paving 15mm above the supporting surface and its integral spacers ensure a constant 5mm gap between each slab, so all water drains away immediately, leaving an "ever-dry" paved area.

Add to this the protection the waterproofing membrane is given from Ultra Violet damage and the temperature extremes, it is easy to see why this method of laying pavings has become so popular.

As the paving is loose laid it's simplicity itself to replace damaged slabs or to inspect for possible waterproofing failure and all drainage outlets, services, manholes, etc., can be covered over to leave a completely unobstructed paved area.

Weather delays now become a thing of the past and the ease of using CARO SUPPORT can return savings in time and labour.
Decking Supports

Stackable for extra height…

As the CARO SUPPORT has been designed to fully interlock when stacking, various heights of raised paving can be achieved from 15mm upwards. This is particularly useful when the removal of falls from the paved area is necessary. Combinations of supports and levelling shims will allow the gradual increase in raising heights, thereby giving a level finish with all drainage falls under the slabs.

Levelling shims for fine adjustment…

To ensure adequate strength, and minimal tolerance variation in the pavings, it is recommended that hydraulically pressed or reinforced concrete slabs be used.

However, occasions will arise when a combination of unevenness in the supporting surface, or tolerance extremes in the slabs, will require the use of the Levelling Shims. These can easily be broken into halves or quarters and, being only 2mm thick, will give the fine adjustment that may sometimes be necessary.

Edge and corner details…

CARO SUPPORT is designed to offer the complete solution, with no wastage. Edge or corner details are easily installed by the separation of CARO SUPPORT into halves or quarters. Simply flex the support or shim, as illustrated, to achieve a half or quarter unit.

Case Studies

New Build – Cumberland Mills, Isle of Dogs, London

This prestigious development of luxury flats and apartments, overlooking the Royal Naval College in Greenwich, has made use of the CARO SUPPORT system to provide a free draining paved area on each of the private balconies.

The purchasers of the quality buildings are now assured of an 'everdry' balcony, to appreciate the dramatic views along the Thames River, as all water is able to drain away immediately between and under the slabs, eliminating any problems of ponding.

This prestigious building, in the centre of Cambridge has also made use of the Caro support system for areas that are used by students and staff, all year round. Come rain or shine, everyone can be assured of an 'ever dry' paved area

Refurbishment – The Mall, Dagenham, London

CARO SUPPORTS were able to provide the complete solution to the problem of movement in slabs on the Mall's residential areas.

It was necessary to lift all the existing slabs and replace the previous support system with CARO SUPPORTS so that, when using a combination of stacking and levelling shims, it was able to provide a completely flat area, with all falls being taken up under the original re-laid paving.

The use of the CARO SUPPORT in this fashion, ensures that paved areas are safe and level, with all drainage and services under the slabs, to give unobstructed access to the end user.




CARO SUPPORT is a High Density Polyethylene injection moulding that raises the paving 15mm above the supporting surface and can be easily separated into halves or quarters for edge and corner details. Any unevenness in the supporting surface or difference in the thickness of the slabs, can simply be adjusted out by the use of the 2mm thick Levelling Shims.
CARO SUPPORT makes the laying of paving slabs on roof or terrace areas, either directly on the waterproofing membrane or on high density insulation boards, a very simple and efficient operation.

Estimation of Quatities

Due to the fact the CARO SUPPORT is easily divisible into halves or quarters, ensuring no wastage, it is possible to allow one unit per paving slab for estimation purposes.

However as most Bills of Quantities quote paved areas in square metres the table alongside will give a fair indication of the number of Caro Supports required dependant upon the slab size and area.
