Description

  The present invention relates to a resin mortar composition, a house foundation protection method, and a termite control method, and more specifically, a resin mortar composition containing an insecticidal compound that is a room temperature solid powder, and the resin mortar composition. The present invention relates to a housing foundation protection method and a termite control method using the resin mortar composition. INDUSTRIAL APPLICABILITY The present invention is useful for preventing deterioration of residential foundation concrete and preventing termites from entering.

  Basic concrete used in houses may deteriorate due to neutralization over time due to the temperature and humidity of the outside air, and cracks may occur on the surface due to drying shrinkage. It is difficult to maintain sufficient strength of the cracked concrete. Further, when cracks reach the inside of the concrete, the penetration of rainwater or the like may corrode the internal reinforcing bar members, which may cause further deterioration of the function. Furthermore, there is a problem that termites enter from the cracked part and cause damage to the wood part of the house.

  Cement mortar is usually applied to the concrete surface for the purpose of preventing deterioration of the concrete. However, cement mortar also has a problem of causing cracks over time. Then, the technique which prevents a crack by using polymer cement and resin mortar instead of cement mortar is known (patent documents 1 and 2). However, since cement cement mortar as well as polymer cement and resin mortar have no termite control effect, problems still remain in terms of preventing termite intrusion. For example, there is a problem that termites easily invade from a minute cracked part and reach the residential wood part.

  Then, the composition which mixed the termite control agent and the water-curable substance is developed (patent documents 3 and 4). However, with these compositions, there is a problem that the concrete cannot be prevented from being deteriorated and the coating workability is very poor.
