Installing Caro Supports
To actually lay paving using the Caro support system is so simple that skilled labour is now not essential. In the same way as if one was tiling in the home, it is important to ensure that the first row of slabs is laid carefully, and in line, to act as a guide for each subsequent row. Thereafter each new slab is positioned on the supports already laid, with the next support held ready to meet the slab as it is lowered onto it. In this way, up to 40m.sq. of paving can be laid in an hour.
Immediate drainage between and under slabs - prevents build up of standing water and plant growth.
Protection of waterproofing membrane from temperature extremes and direct contact damage.
All drainage outlets, manholes, conduit covers, etc., concealed beneath slabs leaving a safe, unobstructed paved area.
Levelling shims for fine adjustment to slab heights.
Simple separation of supports for edge and corner details - no wastage.
Above average base area - greater weight distribution.
Instant access to and replacement of damaged slabs.
Simple installation - reduces time and labour.
All British design and manufacture.
How it works:
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.
Furthermore, this movement can even lead to damage or puncturing of the waterproofing membrane.
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 its 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.
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.
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 Quantities
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.
