Various investigations were carried out at the research field which are Wat Rajaburana and Wat Maha That in Ayutthaya historic site, and Wat Sri Sawai and Wat Sri Chum in Sukhothai historic site. Environmental condition (air temperature, air humidity, precipitation, sunshine, surface and inside temperature of brick) has been measured and analyzed by setting a computerized automatic measuring system at Wat Rajaburana, Wat Sri Sawai and Wat Sri Chum. Fixed point observation has been done at the part where bricks are severely decayd in Wat Maha That. Two small pillars were made by brick near Wat Maha That for simulation test. Water content of the pillars and the surronding groud has been measured periodically. Water level in an old well at Wat Maha That has been measured by setting a computerized automatic measuring system in the well. Investigation to the biodeterioration of the giant Buddha statue at Wat Sri Chum was done, and then the test for cleaning and priventive treatment of the statue was done. Since the test result was so good that actual conservation treatment to the statue was carried out. First the surface of the statue was cleaned by using surgical knife, then the surface layr of the statue was impregnated with a solution of Methyl-triethoxysilane, so that the surface layr was consolidated and hydrofobigated.Through the above research, it reveals that the basic measure for the conservation of a brick remain is to control the water which is affecting the remain.

在研究领域进行了各种调查，这些研究领域是大城府历史遗址的Rajaburana寺和Maha That寺，以及素可泰历史遗址的Sri Sawai寺和Sri Chum寺。环境条件（空气温度，空气湿度，降水，阳光，表面和砖内部温度）已被测量和分析，通过设置一个计算机自动测量系统在Wat Rajaburana，Wat Sri Sawai和Wat Sri Chum。在玛哈塔寺砖严重腐烂的部分进行了定点观测。在玛哈寺附近用砖做了两个小柱子，用于模拟试验。定期测量了煤柱及周围地层的含水量。水位在一个老井在Wat Maha这已被测量通过设置计算机自动测量系统在井中。对Wat Sri Chum的巨型佛像的生物劣化进行了调查，然后对雕像进行了清洁和原始处理的测试。由于检测结果良好，因此对雕像进行了实际的保护处理。首先用手术刀将塑像表面清理干净，然后用甲基三乙氧基硅烷溶液浸渍塑像表层，使其固结并进行氢氟碳化物处理，通过以上研究，揭示了控制影响塑像的水分是保护砖遗存的根本措施。
