When looking to install new garden and drive gates to existing brickwork it is important to ensure that the structure is in good condition and capable of supporting the additional weight placed upon it. As such please take into consideration some of the below factors that may influence if the structure is suitable.
Crumbling Brickwork – If the wall or pillar only has small areas of brickwork in poor condition then it will generally be suitable to hang the gates directly off it. If large areas of brickwork are in poor condition then it is generally not advisable to install metal posts instead.
Condition of Pointing – Over time the weather will deteriorate the condition of the pointing of the mortar beds and ultimately lead to the structure weakening. It is therefore essential that any loose areas be picked out and re-pointed prior to fitting.
Presence of Trees – Walls and pillars built near to trees are susceptible to damage caused by tree roots leading to the structure either leaning over or becoming cracked. In these instances, it will not be suitable to hang new gates off as the added weight may pull the wall over. A better course of action is to demolish the effected section of brickwork and rebuild.
Is the Wall Vertical? – If the wall you are planning on hanging the gate off is leaning to one side and no trees present nearby, this could indicate a problem with the foundations and will need further investigation by a builder to evaluate the extent of the problem.
Has the Wall or Pillar Ever Been Hit by A Vehicle? – If the brickwork has ever been struck by a vehicle entering or exiting your property it is essential to check that it has not been dislodged from its foundations or the added weight of the gate may lead to it collapsing. If any problems are found, then it will be essential to rebuild the structure.
