Settlement of concrete pavements and any slab-on-grade structure is often attributable to inadequate fill material such as frozen fill or improper base compaction. Other causes contributing to a weak base soils condition also include: reduction in water table level; leaking water pipes, sewers and drains; excavations adjacent to buildings; and vibrations caused by heavy road traffic or adjacent construction sites. Poly-Mor Canada Inc (PMCI) has been in the business of using a range of expanding polymer systems to address numerous challenges in the new and retrofit construction industry for many years. POLY-MOR uses a form of "chemical compaction grouting" where a special high density, hydro-insensitive expanding polymer resin is used to fill, densify and stabilize low density, compressible soils to depths of 30 feet and beyond. PMCI has recently developed a new reinforced resin system that is much stronger and long-lasting and can be very suited for soil stabilization in marine environment. However, the specific strength parameters of this new product when exposed to lateral pressure is not completely understood. Moreover, the effect of using this material on the marine life is not fully understood. The proposed project at University of Victoria will focus on three aspects of the new system developed by PCMI, which include: Logistics of placement of the PCMI system on unstable soil, Stability and strength of the PCMI system to lateral pressure, and Short-term leachate tests on the PCMI systems when exposed to chloride and sulphate environment. There are several thousand miles of usable land in Canada along the coast that cannot be fully utilized due to unstable soil and erosion. This project aims at developing an effective solution that can be used to protect the shores of Canada from further erosion, while using a reasonably simple and pragmatic technology. Moreover, the findings of this project will shed light on the efficacy of using this system in sensitive marine environments where leaching of chemicals from the product could be foreseen as an issue.

混凝土路面和任何地面上的板结构的沉降通常归因于填充不足 材料，如冻结填充或不适当的基础压实。导致弱基土壤的其他原因 情况还包括：地下水位下降;水管、下水道和排水沟漏水;挖掘 建筑物附近;以及繁忙的道路交通或邻近建筑地盘所引起的震动。 Poly-Mor Canada Inc（PMCI）一直在使用一系列扩展聚合物系统， 多年来，我们一直致力于解决新建和改造建筑行业的众多挑战。POLY-MOR使用 一种“化学压实灌浆”形式，其中使用一种特殊的高密度、水不敏感的膨胀聚合物 树脂用于填充、压实和稳定低密度、可压缩的土壤至30英尺及以上的深度。PMCI 最近开发了一种新的增强树脂系统，更强大，更持久，可以非常 适用于海洋环境中的土壤固化。然而，这种新的强度参数 产品暴露于侧向压力时的情况并不完全清楚。此外，使用这种方法的效果 关于海洋生物的材料还没有完全了解。 维多利亚大学的拟议项目将侧重于新系统的三个方面， PCMI，包括：PCMI系统在不稳定土壤上放置的物流， PCMI系统承受侧向压力，以及暴露于氯化物时对PCMI系统进行的短期渗滤液试验 硫酸盐环境。 加拿大沿着有数千英里的可用土地，由于 不稳定的土壤和侵蚀。该项目旨在开发一种有效的解决方案，可用于保护 加拿大海岸的进一步侵蚀，同时使用一个合理的简单和实用的技术。此外，委员会认为， 该项目的研究结果将阐明在敏感的海洋环境中使用该系统的有效性 其中化学品从产品中的浸出可预见为一个问题。
