The strength of the hollow one is about 320kgs (Based on the space between the keels of 35cm, the decking surface can bear the weight of 320kgs.) and the strength of the solid one is 400kgs-500kgs.(Based on the space between the keels of 35cm, the decking surface can bear the weight of 400kgs-500kgs.)
When we install the flooring, firstly the keels are fixed in the ground surface with the T-clip and then we put the solid decking board on the keels. You know the wpc decking board can't be put on the ground surface directly. It can effect of the planeness of the flooring surface after installation. It is not good to control the drainage of the bottom, because the wpc decking board is mainly used for outdoor, which rains a lot. So, keels must be used to hold the solid decking board when installed.
No. You need to take the clips of both sides of the broken decking and then take the broken decking out, it's easy.
