The low strength and high compressibility of soft ground make it challenging for construction. Infrastructure on soils with inadequate load bearing capacity commonly require installation of deep foundation, for example deep piling which is not always economical or environmentally safe. Traditional mitigation measures have involved stabilizing native challenging soils with cement to improve its engineering performance. The use of cement poses threat to the environment due to high energy intensive manufacturing process and resulting high CO2 emissions are of concern, as is the slow progress towards exploiting renewable natural resources.

软土地基强度低、压缩性大，给施工带来了很大的挑战。 在承载能力不足的土壤上的基础设施通常需要安装深基础，例如深桩，这并不总是经济或环境安全的。传统的缓解措施包括用水泥稳定具有挑战性的原生土壤，以改善其工程性能。由于高能源密集型制造工艺，水泥的使用对环境构成威胁，由此产生的高二氧化碳排放量令人担忧，开发可再生自然资源的进展缓慢也令人担忧。
