For this reason, coping stones and capping stones are always selected for their high frost resistance and aesthetic appearance. They also have drips, or drip lines, cut into the underside of the stone to encourage rainwater to drip from the edge of the stone rather than seep into the mortar or stone of the wall.
These can be cut on site or pre-sawn at the quarry on request and, in the right setting and in the hands of a craftsman stone mason, will reflect the full beauty of natural stone.
Coping stones from Goldholme are flat slabs of limestone or sandstone, cream or light brown in colour and 40 mm thick.
There are several types of materials to do Coping. The primary function of coping in construction is to provide a channel for the rainwater. Through coping drips waterfalls from the walls, and it prevents its seepage into the walls. Moreover, it gives an aesthetic look to the wall.
Coping is possible in several designs that add to the face of the wall too. Mainly coping causes no structural problem in construction. Besides, it is up to the designer that what he wants to achieve.
Rainwater comes down with a lot of dissolved acids and salts. They can react with the building material used inside the wall and may cause their dissolution. So, to prevent the rainwater get into the wall and decrease its life, coping is done. Copping keeps the rainwater out from the edges and letting the wall dry when sunlight falls on it. It also prevents the wall material from wearing out due to rain, snow, and cold weather condition.
Coping is mainly exposed to temperature extremes and many wet and drying cycles. So it is better to do coping with materials that are resistant to sulfate action and frost. Coping can be possible with different materials such as zinc, aluminum, concrete, stones, etc. There are, however, some benefits to cappings, if appropriate for a project. They are also relatively faster to install than copings as the capping can just be bolted straight onto the wall, without any brackets.
However, when everything is weighed up, aluminium copings are much better than cappings and are what we recommend for an effective and aesthetically pleasing coping solution. In summary, aluminium wall copings are an important aspect and play a functional role in protecting a building structure from water ingress and the issues that can cause. In addition to our standard ranges of coping , HJA Fabrications has the design expertise and experience to produce bespoke coping products, including Secret Fix Aluminium Copings.

A continuous copper cleat, of 20 oz. The copper coping cover is locked over the cleat to form a drip. On the roof side, 20 oz copper counterflashing is nailed to the blocking. The coping cover is locked onto the upper edge of the counterflashing. In this detail, a reglet is formed in the stone or precast coping.
This provides a suitable means by which to anchor grout solid or wedge and seal the continuous copper cleat. The counterflashing at the roof side of the coping is nailed to the wood blocking. The coping cover is locked into place.
This cap flashing detail combines elements of Detail 9. A reglet is used to hold the continuous cleat in place, thus eliminating the need for wood blocking.
This cleat is bent down over front face of the coping. The coping cover is locked onto the cleat. Shown is a condition where a new wall is constructed adjacent to an existing lower wall. A combination coping with a base and counterflashing is used. A continuous copper edge strip is fastened to wood blocking which has been anchored to the top of the old wall. The coping flashing locks into this strip then runs over the old wall. A common lock seam joins it to the base flashing which runs up the face of the new wall at least 9".
The top edge of the base flashing is cleated to the new wall. Through-wall flashing is installed in the new wall, then bent down to lap the base flashing and cleats. The combined base and coping flashing must be installed to provide positive drainage away from the new wall. Its lower edge should be formed into a drip, either by projecting out over the wall as shown here or by introducing a bent drip edge as shown in Detail 9. This condition is similar to Detail 9. A reglet is formed by raking the mortar joint between brick courses.
Counterflashing is inserted into the reglet and held by lead wedges. The reglet is then filled with sealant.
